In addition when VDD is at 0V (ground), all switches are
OFF and the shorted VBUS voltage is isolated from the
other side of the switch.
When VDD is in the range of 2.7V to 5.5V, the shorted
VBUS voltage will pass through to the output of an active
(turned ON) switch channel but not through a turned OFF
channel. Any components connected on the active
channel must be able to withstand the overvoltage
condition.
Note: During the fault condition normal operation of the
USB channel is not guaranteed until the fault condition is
removed.
